FOLDABLE CONTAINER; PARTICULARLY BED BOTTLE Filed Dec. 21, 1967 2 Sheets-Sheet 1 Oct. 27, 1970 G. R. BJORK FOLDABLE CONTAINER; PARTICULARLY BED BOTTLE Filed Dec. 21, 1967 2 Sheets-Sheet 2 United States Patent US. Cl. 4112 3 Claims ABSTRACT OF THE DISCLOSURE A bed bottle of the one-way type, manufactured of a disc-shaped blank of paper, in which one end of the container is so closed as to form a V (seen in the longitudinal section), while its opposite end has a substantially rectangular neck opening. The opening is directed obliquely upwardly with the help of a triangular support face provided on the lower side of the container and abutting to a backing, and a support wing, which projects out substantially perpendicularly to the support face from a neck portion of the container and forms one piece with the latter.

This invention relates to foldable containers and refers particularly to a bed bottle of the one-way type.

In hospitals and other places where bed bottles must be used, the storage and handling of these bottles constitutes a great problem. The bottles generally are made of glass, though plastic bottles increasingly are coming into use.

The model which is the most practical one and which is prescribed by the health service authorities, requires much storage space and, besides, involves considerable storage costs, because there must always be a great number of bottles in stock. Moreover, the bottles after having been used must be washed and disinfected, which involves high handling costs.

In the case of glass bottles, there is also a great percentage of breakage, and plastic bottles show the inconvenience that their cleaning after a short period of app i cation in many cases is very diflicult or impossible, so that the bottles must be discarded.

It also would be possible, of course, to utilize the known paper packagings for milk and other liquids, but there does not exist an embodiment of these packagings which is adapted for this purpose and, besides, said known packaging is made in direct connection with the filling-in of the liquid in question.

The present invention has as its object to eliminate the aforesaid shortcomings and to solve other problems arising in this connection. The invention re ates to a container which can be stored in folded state and is easy to raise to form a bed bottle ready for use. The invention is characterized in that one end is closed like a V, while its opposite end has a substantially rectangular neck opening which is directed obliquely upwardly with the help of a triangular support face provided on one side, the lower side, of the container and abutting to a backing, and a support wing projecting outwardly from a neck portion of the container substantially perpendicular to the said support face, and that the container is provided with an upright carrying handle provided on the opposite side to the support wing, ie on the upper side.

The invention is described in a greater detail in the following, the reference to the accompanying drawings showing an embodiment of the invention.

FIG. 1 shows a horizontal view of an unfolded blank for the container.

FIG. 2 shows in a perspective view the container in raised state, ready for use.

r. ce

FIG. 3 shows in a schemaitc manner a folded container, the arrows indicating where the grips have to be applied for raising the container.

As appears from FIG. 3, the disc-shaped blank is given a somewhat double-cone shape having the longer base line at the ends, because due to a projecting support wing and a projecting carrying handle more material is required at the opening side of the container than at its bottom side. The blank is divided in its centre by a creasing line 1, the base creasing line, which coincides with the shorter base line common to the double cone. Along the entire length of the blank runs a central creasing line 2, the central creasing line. The blank is folded twice along the base creasing line 1 to an upper side 3 and a lower side 4 in the container. Along the edges of the upper and lower sides narrow edge fields 5 are provided to be joined with each other. From the ends of the base creasing line extend two pairs of creasing lines 6 and 7 in an angle of about 45, each of its point on the central creasing line 2. The creasing lines 6 and 7 form with the central creasing line 2 two base fields which will be described below.

From the point of intersection between the central creasing line 2 and the creasing lines 6 extend on the upper side 3 two creasing lines 8 at like angles obliquely upwardly to the opening side and form between themselves and the central creasing line two like fields 9 which can be provided with holes 10 for handles, said fields being adapted to be joined to each other to form a carrying handle 11.

From the ends of the base creasing line 1 extend on the lower side 4 a pair of creasing lines 12 upwardly to a point on the central creasing line 2, which point is located substantially in the middle between the point of intersection of the creasing lines 7 with the central creasing line 2 and the opening side, said creasing lines together with the base creasing line 1 defining a support face 13 adapted to rest upon a backing when the container has been raised.

From the point of intersection of the creasing lines 12 with the central creasing line 2 extend in approximately the same direction as the creasing lines 7 a pair of creasing lines 14 upwardly to the opening side and form between themselves and the central creasing line 2 two similar fields 15 which are adapted to be folded against each other and be joined to form a support wing 16.

After blank was folded twice along the base creasing line 1, the edge fields 5, the carrying wing fields 9 and the support wind fields 15 were folded against each other and joined, a container according to FIG. 2 is obtained, of which the border lines between the edge fields 5 form two opposite corners in the neck opening 17, while the border line between the carrying handle 11 and the container, and the support wing 16 and the container form the two other corners in the neck opening.

A container of this type is easy and cheap to mass produce, like the other commercially available containers of paper and the like, but contrary to the latter types it can be folded and raised. In the state shown in FIG. 2 the container would be much too bulky for being stored in an economic way.

Here it is referred to the two base fields provided between the creasing lines 6 and 7 and to the common central creasing line 2. By pressing in the base creasing line 1 of the container, the said two fields are folded against each other until the container is flattened perpendicularly to its previous lateral extension. The laterally projecting edge fields 5 can be folded in, and a folded container with a main plane through the central creasing line 2, the carrying handle 11 and the support wing 16 is obtained which is easy to package and to transport in great amounts, and which requires small storage space.

When the container is desired to be used, each of the edge fields adjacent the base creasing line 1 is grasped with a firm grip and the two base fields are drawn apart, whereby the container with a low snapping noise reassumes the state shown in FIG. 2. If the large support face 13 does not develop, a finger is to be pressed slightly against the point of intersection between the crease lines 7 and the central crease line 2, whereby the support face assumes a substantially plane position. Already with a relatively small liquid amount in the container, the container stands firmly on a support. By means of the holes 10 in the carrying handle 11, the container can be lifted easily and carried with one finger in a substantially vertical position.

What I claim is:

1. Collapsible one-way-type bed bottle container made of a foldable paper, which container can be erected from a flat disc-shaped scored blank to a usable body form, the bottom end of said container being closed along a line parallel with the bed, which bottom end coincides with the base of a triangular support surface forming the bottom of the entire container, the opposite end of the container forming a neck with a square neck opening, which neck is directed obliquely upwardly with respect to said support surface and being supported by a support wing projecting from under the neck in a vertical plane perpendicular to the support surface and being an extension of the supporting triangular face extending from the apex of said triangular supporting bottom face to the neck opening abutting the bed, a part of said blank, constituting a carrying handle for said container, projecting from that side of the container which is opposite to and in the same plane as said support wing.

2. The container according to claim 1, characterized in that the support wing comprises two similar fields located on both sides of 2 central creasing line on the lower side of the container and being joined with each other, the border line of the support wing to the container forming the lower corner in the rectangular neck opening.

3. The container according to claim 2, characterized in that the carrying handle comprises two similar fields located on both sides of 2 central creasing line on the upper side of the container and being joined with each other, the border line of the carrying handle to the container forming the upper corner in the rectangular neck opening.
